As it travels through a crystal, a light wave is described by the function E(x,t)=Acos[(1.55×107)x−(2.97×1015)t]. In this expression, x is measured in meters and t is measured in seconds. What is the speed of the light wave? Express your answer to three significant figures and include appropriate units.
